Overview
- Fast‑moving clippers spread light snow today from the Midwest and Great Lakes to parts of the Mid‑Atlantic and New England, with most spots seeing a dusting to around 1–2 inches.
- Slippery travel is possible from early morning through midday in places like Metro Detroit, Cincinnati and northern Kentucky due to light snow, freezing drizzle and patchy black ice on untreated roads and bridges.
- A reinforcing Arctic front arrives late tonight, sending much colder air into Monday alongside brisk northwest winds.
- Wind chills fall to the single digits or below zero in portions of the Upper Midwest, Great Lakes and New England, with many areas holding in the 20s for highs.
- Central Pennsylvania is under a National Weather Service air quality alert through Monday night, and a brief midweek warm‑up could bring a rain‑snow mix before colder conditions return later in the week.
